Last year, with the John Mayer limited edition, Audemars Piguet announced the end of its older perpetual calendar movement, the calibre 5134. And indeed, as we have seen with the launch of the next-gen Royal Oak Perpetual Calendar Selfwinding, there is now a new and modern calibre 7138. But it’s not entirely the end of the old JLC-derived movement, as AP had one last trick up its sleeve to celebrate its 150th anniversary: an openworked Royal Oak Perpetual Calendar (ref. 26585XT) in a mix of titanium and BMG, using the skeletonized calibre 5135. So yes, the 5134 is gone… but it has managed to survive in a stripped-down version in this new and impressive AAA UK replica watches.
The new high quality fake Audemars Piguet Royal Oak Perpetual Calendar Openworked 150th Anniversary watches is housed in a 41mm wide and 9.9mm thick titanium case, water-resistant to 20m – as all the older-gen RO QPs. The bezel, caseback frame, and bracelet mid-links are crafted from BMG – or Bulk Metallic Glass – an alloy consisting of over 50% palladium. it was first seen in the RO Jumbo 15202XT for Only Watch before being released commercially in the 16202XT Jumbo with a red dial. A screw-locked titanium crown ensures durability, and glareproof sapphire crystals on both sides provide a generous view of the openworked movement.
The sapphire dial of this bold reference 26585XT super clone watches for sale features a brass blue inner bezel which hosts the week number indication, with an adjacent minutes track clearly marked for precision. The familiar perpetual calendar layout remains: the month and leap year indicators sit at 12 o’clock, the date ring at 3, the weekday at 9, and the moon phase sub-dial at 6 – all in deep blue with white printed markings. Blue-coloured “bathtub” hour and minute hands are treated with luminescent material to enhance legibility.
Several design cues pay tribute to AP’s historic openworked perpetual calendar pocket copy watches wholesale UK (Ref. 25729), displayed at the brand’s museum. These include the rich blue tones of the sub-dials and inner bezel, silver-grey round indices, and the refined typeface of the markings. The stylized Audemars Piguet signature is a standout detail positioned across the astronomic moon phase sub-dial.
The top replica watches is powered by the extra-thin openworked calibre 5135, the skeletonized version of the now-retired calibre 5134 – and this one will retire soon, too. It was first introduced in the boutique-exclusive Royal Oak Perpetual Calendar Openworked 41 Ceramic; it later gained attention in the 2023 Cactus Jack ceramic edition, a collaboration with Travis Scott.
Operating at 19,800 vibrations/hour, the JLC-derived calibre 5135 offers a 40-hour power reserve. It has a suspended barrel and an openworked oscillating weight, which moves along a peripheral ring with ruby rollers – reducing friction and enhancing longevity.
